c++ - 使用 WMI 获取串行硬盘

Question

我正在尝试通过 WMI 获取硬盘序列号，但我不确定这一点，如果我进行如下查询:

// For example, get the name of the operating system
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
    bstr_t("WQL"), 
    bstr_t("SELECT * FROM Win32_diskdrive where index = 0"),
    WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
    NULL,
    &pEnumerator);

然后我进行另一个查询:

    IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
    bstr_t("WQL"), 
    bstr_t("SELECT * FROM Win32_PhysicalMedia"),
    WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
    NULL,
    &pEnumerator);

如何加入此信息以获取同一驱动器的信息？

Answer 1

为什么不用 SELECT * FROM Win32_LogicalDisk 查询？
